Anne-Marie Lagrange, born (1962-03-12)March 12, 1962 in the Rhône-Alpes region of France, is a French astrophysicist.
Lagrange's work focuses on the research and study of extrasolar planetary systems.
From the 1990s, she began to search for exoplanets using direct imaging using novel adaptive optics.
In the 2000s, her research became focused on the study of giant planets around young stars.
In 2005, she made the first direct observation of an exoplanet around a brown dwarf using deep adaptive-optics.
Lagrange also investigates the impact of stellar activity on the detectability of planets.
Lagrange is the holder of numerous scientific awards and honorary decorations, including knight of the Legion of Honour (the highest French order of merit) and is a member of the French Academy of Sciences since 2013.
